Compare and Merge Files

Use the Merging tool to merge two versions of the same source file, with or without reference to a common earlier version. You can work on the same files and compare respective versions of the files without introducing discrepancies. The Merging tool displays both versions of a file side-by-side, highlighting any differences in color. You can then automatically or selectively merge your changes into a new file, and view them in an editable window.

With the Merging tool, you can also merge entire directories or lists of files. This feature is useful when two versions of a program have diverged significantly and must be made to converge.
